混凝土柱承载力按砌体柱计算的不合理性分析
Analysison the unreasonable of the calculation methods for the load bearing capacity of concrete columns as masonry ones
摘要
Abstract
In the bearing capacity calculation methods of highway concrete arch in our country, when the arch is equivalent to beam-column, the formulas of masonry column are often used to estimate the load bearing capacity of the concrete arch. For the irrationality of this method, through the analysis and comparison of the the failure modes and calculation methods of axial compression member and eccentri-cally loaded member between concrete column and masonry column, the results show that the the fail-ure modes, the intensity of cross section and the eccentricity reduction factors as well as the buckling coefficients of reinforced concrete columns are different from that of masonry columns;if the formulas of masonry column are used to estimate the intensity of cross section of concrete column, the result will be smaller than the actual value;however the buckling coefficients and the eccentricity reduction fac-tors of concrete column are smaller than that of masonry column. therefore, if the formulas of masonry column are used to estimate the eccentrically loaded concrete columns, the results will be greater than the actual value, which is unsafe and unreasonable, the calculation of the bearing capacity of the con-crete column should adopt reasonable calculation methods.关键词
